 The dark colored belts on jupiter are brighter than the surrounding regions and the light colored zones when viewed in infrared or heat radiation because chemical reactions causing the dark, visible colors also release energy and heat in these regions. The substance that is responsible for all these chemical reactions is Methane

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
